I ordered the wrong set of pads for my rear brakes, I'm needed the pads that have a pin that fits thru the pads and holds them in place. I order the ones to fit the Trail Stroker instead of the Ryde Stoker instead. It was my fault for not getting of my caboose and verifying which ones I needed. I have yet to attempt to return these for the correct ones, but I don't except any hassles. All in all a very painless transaction.
